To all 'u'ltom 'il mm; rom'rrn: l lie it known that i, WILIJAM A. Ibanlunn'r, a eitizen of the United State-t, residi ing at .\ahland, in the eonnty of l\shlaml and Statev of 'iseonttin, have im'ented new and nsefnl lmprovements in l'iston-lting., 'of a'hit'h the following is n slxazitieation.

't'hia inrention rehnea to moon ringa. and has for an ohjeet to provide a ring of this I elnu'aeter that. aili'ho partienlarly adapted for two in eonneetion willi piatona'of gas! etnzinea, and' providing a aegnn'ntal ring to t l he eonnt-eted with a ptston m auch amnner that it. will he \'ieldinglv engaged with the walls of the iiston cylinder in order that said ring` a'il aeeonnnmlate ith'elf to \\'orn e'ylinders or to those having irregnhu'ities.

atill fnt'ther ohjeet. of niy im'ention,.residea in tho |n'enliar arralnzetnent of,-'eg' nienia formitn: the ring. and it ia nn' paragttilndt n' ring whieh would otln'ra'iee tentl proper aetioa -of the springs elnxlo'ved hy tno. f

notln'r ohjeet of my inventton ia to proi 'ride novel and effeetire means for retainiag the a n'inga to' certain of the segmenta forming t ie ranga, and to emistrnet Iaid means ao that, they also servo to prevept lateral lnovemont of said wgmenta when. a piaton i moving in `ita cylinder.

Uther oh'eota and advantagea will he appnrt'nt aa t to nature of the invention io hetter aet forth, and it a'ill he tnnlt'r.-tad that ulntngt'a within the seopo of the eiaim may he. renorted to without departing from the spirit of the inveation.

In the dran'itng2 fot-mint; a portion of this atnieitlunion tnni ni a'hieh like 'tan'a'.ter.' of reference indieate similar partii in the. ser; entlviowa:---Figttra t i a longitndinal tion through a piaton hoa'ing the appiiyation of my improved ring thereto. l'il'. is a vertieal tram'werae aeetion through the I piston und ring.

toferrin now more partieniarly to the dritwing, t tera is shown a piaton A of mam! construction provided with a diaphrngm or held B in which is ormcd an annnhn' groove or recess C that opens onto the` pe- My improved piston ring is indieated at l and eotaprisea a thn'ality of areaate segna'nls z! having ruhlieted purtions 3 tlmt receive arenete wgments 4, as shown. As 'learl shown in Figs. 2 und '3 of the drawt, ing. nt negna'otn 'when arrnned in their operative positiona` are dia iost, with their ends in spot-ed relation wit t respect to each other. mal the joints between said segna'nts are elo=ed by the. za' `'tnentet 4. The hegments :z hate fot-med t ten-.in a phn'ality of radiall \I extending threaded passa co that reeeire threaded portionx ti of atut u 7. The .stada 't' are provided with inwardly extending enhu'ged eylindrieal portions 8 seuted in eorrestumdingly shaped lateral rcases a torun-d in the pifiton A. y providit the enlarged t'ylinth'ieal portiuns 8, it wi he .-'en that Shoulders lt) are provided odja- 'etit to the threaded portions o! the stada '7 so that art-.nale sprin'os ll when |maitioned upon t-taid attnht 7 ran ie ell'eetivt'ly ettgagetl hy the portions 8 of the stada 7 and eontined het ween the inner n'alht' of the mgnienia tt nlnl the .'thotzltlet'rt lt). i ln order to prevent lateral movement of the fiegna'nts -l when the piston A is movin l provide the said segment: 4 at the ent s thereof with aegmental groovcs 12 adaptod to aline with eaeh other to receive the onter enda of 'the stada 7 that extoad into the rahheted portionn 3 of the at'gntentxi. In

From the. .eonxtrm'tion heroin set forth and deserilx'd it will ho set-.n that l provide aa extreiaely imple and inoxpenaive 'ring that ran he applied in n simple and 0011- wait-nt nnnnwr'to the piston, and by pro-v idiog the pit-;ton A with the annnlar 'roo't'e or rent-as (i to roeit't: the .ring it is wiona that 'aa or floid plemnre in its nttclnpt to po the l'e; 'monta fot-mine; the ring would w ohrinted, thns nllowing the 8 n'ttt 11 to reapond at all timex in order t at tie nog' ments formin the ring can be expntded or inox-ed radiallfy to provide a close lit in a a'orn piaton oylinder or in one having eartain irregnlaritiea a'hieh. `with the well known form of piston ring;` would prevent a pet-feet operation ot' the engine.
